The GP-1 GPS Unit
The GP-1 GPS unit (available separately) can be connected to the camera’s accessory
terminal (
0 177) using the cable supplied with the GP-1, allowing information on the
camera’s current position to be recorded when photographs are taken. Turn the
camera off before connecting the GP-1; for more information, see the GP-1 manual.
❚❚Setup Menu Options
The GPS item in the setup menu contains the options listed below.
• Auto meter-off: Choose whether the exposure meters turn off automatically when
the GP-1 is attached.
• Position: This item is only available if the GP-1 is connected,
when it displays the current latitude, longitude, altitude, and
Coordinated Universal Time (UTC) as reported by the GP-1.
Option Description
Enable
Exposure meters turn off automatically if no operations are performed for the
time selected for Auto off timers in the setup menu (
0 143; to allow the camera
time to acquire GPS data, the delay is extended by up to one minute after
exposure meters are activated or the camera is turned on). This reduces the drain
on the battery.
Disable Exposure meters do not turn off while the GP-1 is connected.

Coordinated Universal Time (UTC)
UTC data is provided by the GPS device and is independent of the camera clock.
